Yes, Q this is true. So, your saying the components should be working more efficiently with a pressurized system.
Gosh, the cost incurred to modify the system on a dirt bike to handle the kind of pressures would seem prohibitive.
But I have certainly been wrong before!
Let's see ...If you would run at 25psi, your coolant could reach about 240deg F before boiling.
(That's just Plain Water. I'm sure you could reach higher temps with "coolant" and or additives.) That will leave you with about a 60 deg. F buffer before
your oil would start to go south. Yikes, too close for my comfort level!
All interesting stuff, if I only had the Sheckles to experiment with! Oh well...
My bike has never had a big problem with losing coolant or overheating. I did put a recovery bottle on it. But hey, if you ride like an old lady you don't worry much about it anyway
I think you have done a swell job improving on what you have to work with so far SB. I am interested in what kind of results you have when you run the bike. I will be using your research on my bike as soon as my current situation gets settled.
Just to throw another variable in the mix, I wonder how much ceramic coating the head and piston crown is worth? Maybe another thread!
Thanks for the interesting conversation and the practical improvements "You Can Do At Home" SB

Keep up the good work!
